IMPROVEMENT IN 'HAY-PRE SSES.

Specification forming part of Letters Patent No. 173,523, dated February 15, 1876; application filed \l'une 9, 1875.

To all whom it may concern:

Be it known that I, MICHAEL L. WHITNEY, of North Yarmouth, in the county of Cumberland and State of Maine, have invented certain new and useful, Improvements in Hay- Presses; and I do hereby declare that the -following is a full, clear, and exact description thereof, whichvwill enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. k

Figure l is a side elevation, in part section. Fig. 2 is a front view of the door and spring. Fig. 3 is a detail view.

Same letters show like parts.

I am aware of Letters Patent granted to George Noyes for certain improvements in hay-presses, said Letters Patent being dated December 17, A. D. 1867, and numbered No. 7 2,221, and I do not claim the subject of that patent. I

My invention has for its object-an improvement upon the doors a, by which their operation is much facilitated. In the said inven lion above referred to the doors, when closed, were secured by an arrangement of bars. In my invention I substitute for them the spring lever b, which, being fastened to the beam d at one end, presses against the outcr faces of 1he doors and tends -continually to close the same.

My invention further consists in a hook, c, attached to the inner face of the doors, and,

when the follower or plunger of the machine is at the'bottom of the box 9, catchinginto the catch f. It shows the follower; g, the box. The follower is at the bottom of the box when 1he hay is first introduced into the box.- The introduction of the hay then tends to force open the doors a, but they are keptclosed by the hook and catch before referred to. As

and other devices for operating the follower h, because they are the same as described in the patent to Noyes, before referred to.

My invention relates exclusively to the above-described attachment to the doors a and follower h. V

The spring-lever b has an outwardcnrve at the bottom end to facilitate its sliding on the top edge of the arms j.

It is manifest that the hooks 6 may be formed of the'same piece of metal as the springlevers b, and turned up under the bottom edge of the doors a, as shown in Fig. 3.

What I claim as my invention, and desire to secure by Letters Patent, is.-

1. In a hay-press, substantially as shown, the doors or, provided with books 6, together with the follower h, provided with catches f, to operate as shown and described.

2. In a hay-press, as shown, the curved spring-lever b, in combination with doorsa and arms j, as set forth.

3. In a hay-press, as shown, the springlever b, with the hook 0, made in one piece,

in combination with the catch f, door a, and

arm j, as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
